Chaney, Walton & MCCall [LLCy <br /> t <br /> features such as stormwater conveyance systems, monitoring wells and other man-made <br /> features. If necessary, locations for monitoring wells and the Victor Well No.2 will be <br /> re-established by land survey. <br /> Geology/Hydrogeology <br /> As described in the Tenera Associates monitoring well installation report dated <br /> September 20, 1993,the subsurface hydrogeologic framework consists of medium dense, <br /> fine-grained silty sands, which are underlain by dense, medium-grained clayey sands and <br /> gravely sands. These deposits were encountered to the maximum depth of 80 feet below <br /> grade. Based on groundwater level measurements in the on-site monitoring wells, <br /> shallow groundwater typically occurs at depths ranging from 60 to 70 feet below the <br /> wellhead measuring point. <br /> PREVIOUS SITE ASSESSMENTS <br /> In July 1999, a Phase I Environmental Site Assessment was prepared for the WiIdRose <br /> Vineyards company, the new owners of the former Dole property. The CW&M Report <br /> entitled "Support of Site Closure", addressed the former UST at VFO. <br /> PROPOSED FIELD INVESTIGATION <br /> The field investigation tasks proposed for the former VFO UST Site include the planning <br /> for and installation of two shallow soil borings. The placements of these borings are <br /> intended to assist in confirming the absence of elevated MTBE in onsite soils, at the <br /> former UST location. <br /> Prepare and Conduct Pre-Field Plans and Activities <br /> A required Health and Safety Plan will be prepared to safely conduct field-drilling activities <br /> planned for this Site Assessment. Based on an evaluation of the previous UST removal <br /> activities,two locations are proposed for the installation of shallow soil borings. The <br /> proposed locations will be established in the immediate vicinity of the former UST,which is <br /> approximately located on Figure 2 of this Work Plan. <br /> 5 <br /> DF100101.5JCPH.wkp.011800 4 530.758.8128 W <br /> rccgroup@earthlink.net <br />
